I already asked a question on this subject (Has anyone ever measured the positron apparent range in matter?) and it was answered by Samuel Silverstein faculty, physics, Stockholm University (thank you !) unfortunately the answer was not completly satisfying as he proposes to see the table from ICRU for electron and positron stopping power (in the continuous slowing down approx). In these tables you can get the real path of e- or e+ in matter whereas what I would like is the average path (I mean the real distance between the beginnig of the trajectory to the end which is much smaller than the range since e- and e+ do not travel straigh on in matter). I know this question is a subject of interest in positron emission tomography imaging so I guess some people have measured it already...I have not found already..please help... Samuel Silberstein told to ask for him as answerer
